1 is a schematic flow chart of a method of updating system information in accordance with an implementation of the present invention. As shown in FIG. 1, the method 100 can include:

S110. The terminal device acquires at least one indication information sent by the network side device, where the at least one indication information is used to indicate that at least one system information group is updated, and the at least one system information group and the at least one indication information are in one-to-one correspondence. Each system information group in the at least one system information group includes at least one system information;

S120. The terminal device determines at least one target system information that is updated in each of the system information groups.

S130. The terminal device acquires the updated at least one target system information in each system information group.

Specifically, the indication information in the embodiment of the present invention can indicate that the system information group is updated. The system information group may include at least the following situations:

Situation 1,

Optionally, as an example, different system information groups include different categories of system information. For example, the at least one system information group includes a first system information group, the at least one system information included in the first system information group belongs to public system information, and the at least one indication information includes information used to indicate the first system information. The first indication information that the group is updated; and/or the at least one system information group includes a second system information group, the at least one system information included in the second system information group belongs to dedicated system information, and the at least one indication information Included for indicating that the second system information group is sent The second indication information of the update is generated.

Specifically, each system information group includes system information of one category, and the indication information corresponding to each system information group can be used to indicate that the system information of the corresponding category is updated, and the update range of the system information can be reduced; or the terminal device is occurring. Determining at least one target system information that needs to be updated in the system information of the updated category can improve the efficiency of the terminal device determining the target system information that needs to be updated.

Case 2

Optionally, as an example, each system information group includes only one system information. The indication information corresponding to each system information group is used to indicate that a corresponding system information is updated, and the update range of the system information can be further reduced. The terminal device determines at least one target system information that needs to be updated in the updated system information, and can further improve the efficiency of the terminal device determining the target system information that needs to be updated.

Case 3,

Optionally, as an example, the content included in each system information group may be pre-approved by the terminal device and the network side device, or may be indicated by the network side device to the terminal device. For example, the first system information group in the at least one system information group includes a part of the public system information, and the second system information group in the at least one system information group includes a part of the dedicated system information and the like.

In this scheme, each indication information is used to indicate that the corresponding system information group is updated, and the terminal device can determine at least one target system information that is updated (or needs to be updated). In other words, the indication information in the solution is used to indicate that a part of the system information is updated, which can avoid waste of resources caused by blindly updating all system information, improve update efficiency, and shorten update delay.

In the above, the terminal device can be configured to acquire the updated at least one target system information according to at least one indication information from a holistic perspective. The obtaining, by the terminal device, the at least one indication information may include at least the following two methods:

Manner 1 (The terminal device obtains the at least one indication information by using an indication field included in the same message)

The system information group and the indication domain have a corresponding relationship. For example, if there are M system information groups, the M system information groups correspond to M indication fields one by one. The indication message received by the terminal device may include L indication fields, where 2≤M, 0≤L≤M. In other words, the indication message received by the terminal device may include M indication fields corresponding to the M system information groups, and each indication domain carries information indicating whether the corresponding system information group is updated. The indication message received by the terminal device may also include occurrence The indication domain corresponding to the updated system information group (ie, the indication domain corresponding to the system information in which the update does not occur in the indication message may not appear). For example, there are M system information groups, and only one system information group of the M system information groups is updated, and the indication message received by the terminal device may include only the indication domain of the updated system information group, and the remaining M-1 The indication field of the system information group does not appear.

Optionally, as an example, the acquiring, by the terminal device, the at least one indication information that is sent by the network side device may include: at least two indications that are included by the terminal device from the same indication message and corresponding to the at least two system information groups. Determining at least one indication domain in the domain, wherein each of the at least two indication domains is used to carry information indicating whether an updated system information group is updated, and each of the at least one indication domain indicates a current domain Carrying information that the corresponding system information group is updated, the at least two system information groups include the at least one system information group; and the terminal device acquires the at least one indication information from the at least one indication domain.

Specifically, the acquiring, by the terminal device, the indication message sent by the network side device may include at least two indication domains, where each indication domain of the at least two indication domains is used to indicate whether a type of system information is updated (ie, each The system information group includes a type of system information). For example, the indication message includes a public indication domain corresponding to the public system information and a dedicated indication domain corresponding to the dedicated system information. Table 1 shows one possible indication of the public indicator domain and the dedicated indicator domain. As shown in Table 1, each indication domain carries the indication field value. If the indication field has a value of 0, it indicates that no update has occurred. If the indication field has a value of 1, it indicates that an update occurs.

Table 1

After the terminal device receives the indication message sent by the network side device, the indication message includes at least two indication fields corresponding to the at least two system information groups, and the terminal device may perform an indication according to each indication field in the at least two indication fields. The value of the field is determined by the at least one indication field, and the at least one indication field carries the at least one indication information.

For example, the indication message received by the terminal device includes a public indication field and a dedicated indication field, where the indication field of the public indication field takes a value of 0, and the indication field of the dedicated indication field takes a value of 1. After receiving the indication message, the terminal device receives the indication message according to the The dedicated indication field obtains indication information indicating that the dedicated system information is updated.

Specifically, the indication message may include at least two indication domains, where the at least two indication domains Each indication field is used to indicate whether the corresponding system information is updated (ie, only one system information per system information group). For example, the indication message includes a first indication domain corresponding to the cell reselection information and a second indication domain corresponding to the D2D system information. Table 2 is a possible indication of the different indication fields in the indication message. As shown in Table 2, each indication field carries the indication field value. If the indication field has a value of 0, it indicates that no update has occurred. If the indication field has a value of 1, it indicates that an update occurs.

Table 2

Each SIBx or System Information (SIx) has a separate indication field. Each indication field is used to carry information on whether the corresponding system information is updated. After the terminal device receives the indication message sent by the network side device, the indication message includes at least two indication fields corresponding to the at least two system information groups, and the terminal device may determine at least one value according to the indication field of the at least two indication fields. And indicating the domain, the at least one indication domain carries the at least one indication information in a one-to-one correspondence.

For example, the indication message received by the terminal device includes N indication fields, where the N indication fields are used to indicate whether N system information is updated, and the N indication fields have Nx indication fields for indicating corresponding After the system information is updated, the terminal device may obtain Nx indication information for indicating that the Nx system information is updated, and the Nx system information and the Nx indication information are obtained from the Nx indication fields. A correspondence, where 2 ≤ N, 0 ≤ x < N.

Optionally, as an example, the at least two indication fields may be a dynamic indication domain. According to the configuration or the convention, the indication domain itself may be used to indicate whether the corresponding system information group is updated. For example, if the indication domain corresponding to the first system information group in the indication message does not exist, it may be indicated that the first system information group does not update; if the indication message includes the indication domain corresponding to the second system information group, regardless of the second system The value of the indication field corresponding to the information group is considered to be updated.

Manner 2: The terminal device obtains the at least one indication information by using different messages.

Optionally, as an example, the acquiring, by the terminal device, the at least one indication information that is sent by the network side device may include: the terminal device acquiring at least two indication messages that are in one-to-one correspondence with the at least two system information groups, where Determining, by each of the at least two indication messages, information for carrying out whether the corresponding system information group is updated, the at least two system information groups including the at least two a system information group; the terminal device determines at least one indication message from the at least two indication messages, where each of the at least one indication message indicates that the system information group corresponding to the current bearer of the message is updated; the terminal And obtaining, by the device, the at least one indication information from the at least one indication message.

For example, the terminal device receives N indication messages, and each of the N indication messages is used to carry information about whether the corresponding system information group is updated, where Nx indication messages are used in the N indication messages. Carrying information that the corresponding system information group is updated, the terminal device may obtain Nx indication information from the Nx indication messages (in other words, the Nx indication messages correspond to the Nx indication information one by one), wherein , 2 ≤ N, 0 ≤ x < N.

It should be noted that the terminal device receives at least two indication messages for illustrative purposes only and should not be construed as limiting the invention. In fact, the terminal device can receive an indication message carrying the indication information (ie, the terminal device receives an indication message, and the indication message carries information that the corresponding system information is updated).

Further, as an example, the terminal device acquires at least two indication messages that are in one-to-one correspondence with the at least two system information groups, and may include:

Obtaining, by the terminal device, the corresponding one of each of the at least two system information groups, on the first transmission resource corresponding to the indication message for transmitting each of the at least two system information groups An indication message, wherein the indication messages of different system information groups (corresponding) correspond to different first transmission resources; or

Specifically, the indication messages corresponding to different system information groups are transmitted through different transmission resources. The terminal device can receive the corresponding indication message on the corresponding transmission resource, and the terminal device can obtain the at least one indication information from the received indication message. For example, the system information group includes a type of system information, and the terminal device may receive the public indication message on the first transmission resource corresponding to the public indication message corresponding to the public system information; Receiving the dedicated indication message on the first transmission resource corresponding to the indication message, and the terminal device may determine the at least one indication information according to the information carried by the public indication message and the information carried by the dedicated indication message.

For another example, the indication messages corresponding to different system information groups correspond to different first network temporary identifiers. The indication messages corresponding to different system information groups can be identified by different first network temporary identifiers. The network temporary identifier may include a Radio Network Tempory Identity (RNTI). For example, the at least two indication messages include a public indication message and a dedicated indication message, wherein the public indication message is scrambled by the first network temporary identifier RNTI1, and the dedicated indication message is scrambled by the second network temporary identifier RNTI2. After receiving the indication message A, the terminal device descrambles the indication message A through the RNTI1, indicating that the indication message A is a public indication message for indicating whether the public system information is updated. After receiving the message B, the terminal device descrambles the indication message B through the RNTI2, indicating that the indication message B is a dedicated indication message for indicating whether the dedicated system information is updated. Furthermore, the terminal device can determine the at least one indication information from the information carried by the public indication message and the information carried by the dedicated indication message.

Optionally, the network temporary identifier may include a Cell Radio Network Temporary Identifier (C-RNTI), a Semi Persistent Scheduling (SPS-RNTI), and a System Information Wireless Network Temporary Identity ( System Information (SI-RNTI) and Random Access Radio Network Temporary Identity (RA-RNTI).

Optionally, the method may further include: the terminal device receiving the first configuration message, where the first configuration message includes a correspondence between the indication message of the system information group (corresponding) and the first transmission resource; or The first configuration message includes a correspondence between the indication message of the system information group (corresponding) and the first network temporary identifier.

After receiving the first configuration message, the terminal device can receive an indication message corresponding to the system information group related to the requirement (service requirement) on the corresponding transmission resource; or receive the related information according to the corresponding first network temporary identifier. The indication message corresponding to the system information group.

Optionally, as an example, the acquiring, by the terminal device, the at least one indication information sent by the network side device may include: the terminal device determining the at least one system information group; and the terminal device listening to the at least one system information group The indication information corresponding to each system information group.

Specifically, the terminal device can determine at least one system information group (according to its own service requirement), and listen to at least one indication information corresponding to the at least one system information group, so that the terminal device can timely update the system information group to be used. . For example, all terminal devices listen to an indication information corresponding to the public system information (the one indication information is used to indicate that the public system information belongs to The system information of the information is updated or the public system information corresponds to at least one indication information (the at least one indication information is used to indicate that at least one system information belonging to the public system information is updated one by one); for the dedicated system information, the terminal The device only listens to the indication message of the required system information group on the transmission resource corresponding to the system information group that it needs, or the terminal device uses only the RNTI corresponding to the system information group that it needs to perform physical control channel addressing.

In the above, several implementation manners for the terminal device to acquire the at least one indication information are described. The determining, according to the at least one indication information, the at least one target system information in the at least one system information group, although blind update can be avoided, and the update efficiency is improved, but the phenomenon of repeated update may occur. To further avoid unnecessary updates, the method 100 can also include:

Specifically, each system information group corresponds to one tag value group. Assume that each system information group includes a system information. The terminal device may compare the tag value of each system information (group) in the at least one system information (group) with the tag value (group) of the corresponding system information (group), and determine that the system information with different tag values is updated. System information. Table 3 is one possible way of carrying a tag value message for a tag value.

As shown in Table 3, the SIBx (SIx) is used to indicate a certain system information. When the terminal device acquires the label value of the SIBx and the stored (or last acquired) label value of the SIBx, the SIB is considered to be updated, and the terminal device can obtain the updated SIBx. In other words, when the tag value of the SIBx acquired by the terminal device at the first time and the tag value of the SIBx acquired at the second time are not At the same time, the SIBx is considered to be updated, wherein the second time is earlier than the first time.
